i have the original radical tour. 9 of them. they play like the original prince graphite. i tried the newer models, and i ended up sticking to what i have.
Mine would be the KFactor Tour 90s. Currently have champion choice string set, ALU in mains at 55# and Gut in crosses at 57#. I usually have the NXT 16 and the ALU Rough at said tension. Now what to do with my KFactor 95 stick...
I have several main racquets, one is a Babolat Aero Pro Drive Plus no cortex w/Poly mains 60# & Gosen Micro 18 crosses 62#, other is a Yonex RDS 001 mid w/Natural Gut 16 mains 60# and Topspin Cyberflash 17 crosses 60#, another is a Volkl DNX 10 mid, Volkl C10 Pro Tour Mid both strung w/Natural Gut 16 mains 60# and Topspin Cyberflash 17 crosses 60# and a Volkl Tour 10 Gen 2 w/Natural Gut 16 mains 60# & Topspin Polytech 17 crosses 60#. I love all my racquets and rotate them every set.
Well my string tension is the same on all of them ;) I am still playing around with the racket and string type though I like them all and do not want to sell or part with them, I am too cheap. I will play with these until they break. Same goes with my strings, I've cut the strings a couple of times but that is because synthetic gut goes dead and inconsistent pretty fast.
